How to Fix OneNote Desktop Sync Problems with the Web App
Product
Microsoft OneNote
Device & OS
not provided
Scenario
Attempting to synchronize notebook updates between the cloud (OneNote for the web) and the local desktop application.
Observed behavior
Newer pages appear online but do not reflect in the desktop app. The desktop app fails to sync and may prompt connection or proxy-related errors such as 0x80072EFD.
Before you start

Before attempting any sync repairs or closing local notebooks, open your notebook in OneNote for the web to verify that all your recent changes are safely stored in the cloud to prevent data loss.

Solution 1Recommended

Reset Sync Connection via the Web App

Use this method to safely close the unresponsive local notebook and establish a fresh synchronization link directly from the cloud.

If the desktop app is stuck due to a corrupted local cache, forcing it to reload the notebook from the server can often resolve the discrepancy without risking your online data.

1
Verify pages online

Log in to OneNote for the web through your browser, open the affected notebook, and confirm that all your latest notes and pages are fully visible.

2
Close the local notebook

Open the OneNote desktop app, right-click the name of the notebook in the sidebar, and select 'Close This Notebook' from the context menu.

3
Reopen from the web

Return to OneNote for the web. In the top ribbon menu, click the 'Open in Desktop App' button to launch the notebook and force a fresh synchronization to your computer.

Reset Sync Connection via the Web App
Data Safety Checked: By ensuring your data is intact on the web version first, closing the local notebook guarantees you will not lose any unsynced changes.

Error code 0x80072EFD typically indicates a network connection failure where the application cannot establish a secure connection to the server. It is usually caused by firewall restrictions, incorrect proxy settings, or an unstable internet connection.

Will closing my notebook in the desktop app delete my notes?
